Wailord

You may sacrifice a creature named Wailmer
rather than pay this spells mana cost.
Wailord can't attack unless defending player
controls an Island. If it does attack, it gains
trample and hexproof until end of turn.
Whenever a player adds one or more {u}, Wailord
gets +0/+2 until end of turn.
{u}{u}, {t}: Wailord deals damage equal to its
toughness divided as you choose among any
number of target attacking or blocking
creatures.
